      Link to task:

      https://spruce.mongodb.com/task/mongo_python_driver_test_macos_python3.9_test_4.4_sharded_cluster_auth_ssl_async_patch_bf0aa56fbbfa33c3bfbdf3c03a4ab55aceb0cda4_67f08a14880b50000896aa41_25_04_05_01_40_37/tests?execution=0&sortBy=STATUS&sortDir=ASC

      Context of when and why the failure occurred:

      Async tests often have higher latency due to the event loop overhead. Tests that have a defined range for timing should have that range expanded to allow for variable delays.
